We’ve all heard that the best way to get a woman into bed is to make her laugh. Women go for the funny guys, and more women say that they’d prefer a guy who makes them laugh to a tall guy or a handsome guy, according to Salon. However, this doesn’t mean that you can just tell all the jokes you want and hope that she laughs at a few of them. In fact, you have to be pretty discerning with the jokes you tell a one night stand, or you’ll end up going home alone no matter how funny you think you were. Some of the jokes you should avoid telling a girl you just met are:

Ethnic Jokes

The first thing you need to remember is that you just met this woman – and unless you met by discussing your ethnicity in detail, you have no idea what her ethnicity is, especially if she’s like the vast majority of Americans and has a mixed heritage. Even more than her own ethnicity, you can’t tell what her best friend’s ethnicity is, or her past boyfriends’ or step-parent’s. Even if you’re sure that this is the funniest Chinese joke you’ve ever heard, those jokes have no place on a first date. If you don’t want her to think you’re an asshole, leave those jokes at home. There are plenty of other “edgy” jokes you can tell that won’t make the majority of women just stand up and leave (or feel quietly uncomfortable).

Religious Jokes

“Yes you are right; my religion does not allow one night stand”

Here’s the truth: some women will find offensive religious jokes hilarious. That’s the kind of thing you’ll learn about a woman when you’ve been around her for several dates. However, it’s not the kind of thing you’ll be able to learn about a woman after just an hour or two. Most women will not laugh at offensive religious jokes, or they’ll laugh to make you feel better. Stay clear of these if you really want to impress her.

Sexist Jokes

The sexist joke has, unfortunately, made a comeback among 20-somethings who want to seem edgy. Let us put this to rest: they’re not funny. They’re not going to make any woman want to get with you. They’re only good for letting women know that you’re not ready to be with a woman, because you’re not confident in your own masculinity. If you’ve ever considered using any variation of the phrase “make me a sandwich” to make her laugh, reconsider immediately.

Bathroom Humor

What’s a guy to joke about if all of those things are off limits? NOT the stuff that should be kept safely behind a single closed door. Farts and poop are off limits if you ever want a chance of getting laid with this woman. Trust us, she doesn’t want to hear it, and you don’t want to put yourself squarely in the category of “drunken frat boy” instead of the category of “guys I’d like to sleep with.”
